ROBERT B. THOMPSON, OF WVILKINSBURG, ASSIGNOR TO SOHUETTE & (10., OF PITTSBURG, PENNSYLVANIA.

MANTEL.

SPECIFICATION forming part of Letters Patent. No. 389,340, dated September 11, 1888.

Application tiled September 23, 1887.

To all whom, it may concern.-

Be it known that I, ROBERT E. THOMPSON, of Vilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in the Construction of Mantels, of which this is a complete specification.

The object of my invention is to provide a construction for mantels whereby one size of mantel-frame may be readily and accurately fitted to fire-places of different sizes.

Theimprovement consistsin combining with the frieze and pilasters of the mantel-frame a lintel extending below the frieze and jarnbs exten di ng in ward from the pilasters, thejambs and lintel being connected, by a tongue-andgroove slide-joint, substantially in the manner hereinafter described, and as pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both figures.

Figure 1 is a front elevation of a mantel constructed according to my improvement. Fig. 2 is a rear view of the said mantel, parls being broken out to reveal certain details of construction.

A designates a mantel, which may be constructed, as usual, of wood or kindred material, with a more or less ornamental frieze, B, and pilasters O, forming an inelosure which is to be fitted to the fire-place in front of which the mantel is to be arranged. To this end in Serial No. 250,494. (No model.)

my improvement a wooden or other lintel, D, having a longitudinal groove, D, in its lower edge, is fastened along the back of the frieze B, with its lower edge extending below the same, so as to make the opening the desired height. Jambs E, having tongues 1* on their upper ends adapted to the groove D in the lintel, are then cut to the desired length and suitably fastened to the backs of the pilasters O, with their tongues F resting in the groove D, and at an equal and such a distance from the center line of the fire-opening as to make the width of the same correspond to that of the fireplace. The inner edges of the jambs and lintel, when properly adjusted, are lined with [ire-strips G in a well-known fashion.

The appearance of the fire-opening thus formed will, as shown in Fig. 1, resemble that of a mantel made specially for the fireplace.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent A mantel constructed of a frieze, pilasters fixed to opposite ends thereof, a lintel secured detachably to the back of the frieze and projecting below the same, and jambs secured dctachably to the backs of the pilasters, projecting inward beyond the same, and connected by an adjustable slidejoint to the detachable lintel, substantially as described.
